Hydraulic oil aerating in diff/trans

[careyo63]

Your gear drive transmission is not a dry transmission else there would not be seals on the rear drive axle or PTO shaft. So while pressure may inly he required by lifting your 3ph, it is far from the only thing using that fluid. And the pump runs while the engine runs.
Please quit promoting false information to others who may not have knowledge to recognize misinformation. While the gears in your transmission may be more of splash bath, it still uses the fluid!
Otherwise why dies a differential or transfer case in a truck have fluid?

Another Yikes!! only thing I was referring to was the Hyd. Pump. I didn't know I needed to wright a novel on every seal on the tractor Dang!!! or uses the fluid for that matter..........:confused2:

You are the one that said you only use your hyd for your dirt scoop. Realize that many new tractor users read these statements. And I have seen people that would assume such a statement to mean the did not need hydraulic fluid if they did not use the 3ph. That is bad thought process on 2 fronts. 1) what you put out and 2) them not learning there machine.

Oh a question, how do you not run your hyd pump when tractor is running but you are not using your 3ph?
My pumps any time the tractor engine is running regardless if I operate a hydraulic function. The pump still works!

Again you Buttwipe. I'm not writing a novel exactly and what all my Hyd. Sys.works with and how. And your the first and only one to complain about what I wrote. I don't have to even have a pump operating to even use my tractor. My 3PT. lift just won't work!! So FO...........

Seems someone got out the wrong side of the bed this morning!

Sure did as a matter of fact. And having to start the day with his BS............ I'm upgrading him to a As_wipe............

Well heck, lets stir the pot some more.
I read thru your posting and was a bit confused also,
you seem to feel that your hydraulic pump doesn't operate all the time.
Is this correct?

If so I will disagree I do not have a Yarmar but every tractor I have operated except for a few very old ones had a live hydraulic,
in that the pump was driven by the engine and ran constantly. Some were mounted on the engine, some are mounted in the transmission
case area but they run as long as and any time the engine does.

It always flows just not under pressure. On my YM2000 it only operates the 3pt that's it period. Shear the pump key is a common problem. That doesn't mean you can't run or operate it. The Tractor that is for A/W. And on mine I actually checked and can't find the first thing the Pump operates or even oils besides the 3Pt. lift. On a YM 2000 or the 1300 for that matter like the Org. Poster. A 2002 with power shift has nothing to do with this thread as A-wipe is insinuating. And what ever is found it does Oil besides the 3Pt. that anyone can find it does I'm all for hearing about it but there isn't anything!! On a YM2000-1300 like the org. post!!!!!

So sad you are such a poor human that you need to call people names. An just how does s pump that runs off of your running engine not have pressure until you push a lever. Does your 3 point hitch raise when you move the lever to raise it or do you have to wait for pressure to build up?
There are words for people like you, but I will allow the reader to decide what to name you!
I only ask that you stop with the misinformation. You apparently think that there is no pressure until you want it by opening a valve. That is far from how the system works.
You can believe whatever lies you wish but others that may not understand deserve to have accurate information from these forums!

Thank you for your understanding of how any pumping system works. Also that it is under pressure when the pump is running. But as you can see by the followup comment from the self proclaimed most knowledge name caller we do not understand.
Well all I can say is he needs to stop using that and charge for people to come check out his most unique tractor.

I wonder what he thinks will happen if he gets a hole in either line going to his pump? By reading his comments nothing until he raises his 3 ph.
But as any of us who ever blown a pressure line knows we gave a mess and are done until repairs happen. Even a return and a suction line makes a mess! That is the real world!

Learn your yanmars, I wish I had a power shift but no go. Go check it out!
Mine has 1 reverse and 3 forward in 4 ranges (C, 1, 2, 3) non-synchronized.
You prove by all your going on that you lack basic mechanical understanding of how a pump works. But worse is you provide information that could result in someone getting seriously hurt. Someone will thing by your information that they can open a hydraulic pressure line and since they have not called (in your example) raising the 3ph there is no pressure present.
I beg to correct this misinformation because if the pump is operating then it is producing pressure and flow. Note operating. That typically is happening when the engine is operating. If it is not you have problems. Same goes for the injection pump and the water pump (if present, as not all Yanmars have water pumps).
As for your name calling—go ahead you tell way more about yourself by that than you ever will about the person you call names.
